BENJAMIN S. SEAMAN, OF CANTON, OHIO, ASSIGNOR TO THE GILLIAM MANUFACTURING COMPANY, OF SAME PLACE.

BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 566,477, dated August 25, 1896.

Application filed July 23, 1895. Serial No. 556,856. (No model.)

ToaZZ whom, it may concern:

Be it known that I, BENJAMIN S. SEAMAN, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Bicycle-Saddles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in bicycle-saddles; and it consists in providing a saddle that is light, strong, and durable at a greatly-reduced initial cost.

\Vith these objects in view my invent-ion relates to certain features of construction and combination of parts.

Figure 1 of the drawings is a side elevation having a part of the saddle-leather removed to disclose the front portion of the frame. Fig. 1 is a perspective View of the clamping block. Fig. 2 is a perspective of the extension-screw. Fig. 3 is a similar view of the pommel-support. Fig. 4 is a cross-section from a to z of Fig. 5. Fig. 5is aperspective from left front, showing the top of cantle-frame tubular support. Fig. 6 is a cross-section from ytoy, Fig. 5. Fig. 7 is a longitudinal section through the tubular portion and cantle, showing the position of the strengthening-bar. Fig. 8 is a view of the cantle-frame from rear under side.

A denotes the central or body portion of the saddle-frame, which is made of suitable metal, preferably steel, having in its under side for a distance, as from a: to as, (see Fig. 7,) a V-shaped depression, as a, (see Fig. 6,) to adapt it to the U-shaped rib d, (shown in Fig. 1%) by which the saddle is held against a lateral rocking movement on the seat-support. At the rear end portion of the tube is provided a kerf b, in which is secured the front central port-ion c of the cantle-frame B. The cantle-frame may be made of any suit able metal, preferably sheet-steel, from which blanks are cut and dropped or pressed to the form, or substantially so, shown in the drawings, the rear portion curved to conform to the leather seat O and rolled down and slightly under, as shown in Figs. 5 and 7, said rolled portion having provided therein perforation d to receive the rivets by which the leather seat is secured thereto.

Central to and transverse the web portion of the cantle-frame B is stamped a rib, as e, semicircular in cross-section and adapted to rest in the lower rear portion Z) of the tube A, as shown in Figs. 4 and 7, for the purpose of securing the cantle from lateral vibration in the tube, the top portion h of the tube to overreaoh the groove formed in the top side of the cantle to produce the rib eand rest on the top of the cantle, as shown in Fig. 4, in which position the parts are secured.

To further strengthen the tube A and its connection with the cantle-frame when desired, an angle-bar D is provided, the rear side portions cut away and graded to adapt the end of the bar to a similar slope orgrade, provided in forming the rib c, that the top of the cantle may wedge against the graded edges of the angle-bar, as shown in Fig. 7. The an gle-bar is placed within and bent with the tube A.

At the front end of the tube are provided recesses l to receive the lugs m, provided 011 the sides of the threaded nut E, into which is turned the screw F, which will be hereinafter explained.

The pommel-frame G is formed substantially as shown in Fig. 3, having wings, as q, in which are provided perforations s, by which the frame is secured to the leather seat, a spreader t to support the ends of the frame, and an end portion it, having therein an ap erture o, in which is placed the end portion 20 of the screw F, and a forwardly and downwardly projected portion w, to which the pommel or front end portion of the seat-leather is secured, as shown in Fig. 1. At the forward end of the screw F are provided apertures r.

The object of the structure described in the before-going paragraph is to provide .a support for the sides and front of the seatleather, and to tighten or stretch the seatleather on the saddle-frame in operation a pin is placed in the apertures r, by which the screw F is turned into or out of the nut E and the end of the tube A to slack or stretch the seat-leather as occasion may require.

Having thus fully described the nature and the object of my invention, what I claim is- In a bicycle-saddle, in combination, a flexible seat, a rigid bow-shaped scat-support, having at its under side a V-shaped depression,

the apertured end to support the screw F, the front extension to fit the front end of the seat, the threaded nut E secured to the front end of the tubular support and the screw F, whereby the seat may be stretched on the frame, substantially as described.

In testimony whereof I have hereunto set my hand this 18th day of July, A. D. 1895.
